For my first one, I'll make it simple.
-Pick your favorite season
-Use pictures and words to show how it is great
-Any type of wallpaper is allowed (i.e. any person from any series, and quotes...things like that)
-Make the mood suit the way you feel during that season (dont have it sad for winter because of the colors, unless you like it because it makes you sad)
-Follow TheO guidelines/rules
-Give credit where credit is needed
-Make sure it shows effort
-Have fun!

Can't wait to see what you guys can come up with!

~Made a (kind of bad) example if you want to see something (though I really don't care what it is, as long as it relates and follows everything above): Winter

[EDIT: 3/4/11]- O.O realized that I didn't post what the winners get!
1st-Wallpaper dedication, a gift, and a congratulation post on their wall
2nd-Card dedication, a gift, and congratulation post
3rd-Gift and congratulation post

If you find these unfair, please tell me, and I'll try to fix them! Thanks!
Oh, and if you are one of the placed people, you can notify me if you want me to write a short story based off of your winning entry as an add-on.
